adjusted relative thereto, an electric motor 4- and a cutter 5. y

The frame comprises a pair of relatively spaced parallel longitudinalbars or rods 6, and on each end of each lOCli 6 there is mounted forlongitudinal movement an attaching bracket 7 and the brackets 7 atcorresponding ends of the bars 6 are connected by cross bars 8.

As will be seen from a study of Figure 7 each of the brackets 7comprises a body portion extending at a suitable angle to a bar 6 andprovided at one end with an integral sleeve 9 through the bore of whicha rod 6 extends, and the screw threadedly engaged with the sleeve 9 isan adjusting screw 10 arranged to engage a. bar 6 for holding thebracket 7 at the desired adjustment.

At its free end the body of the bracket 7 is provided With an L-shapednotch to provide angularly arranged lugs 11, 12, of which the lug 11 isadapted to flatly engage a sash member 13 at one side of the sash, andthe other lug 12 is adapted to overlie and extend u in parallelism tothe free outer edge or face 79 of the member 13 of the sash as shown inFigure 7.

The lug 12 has threadedly engaged therewith a screw 14: that is adaptedto engage the member 13 of the sash as shown, while the lug 11 hasintegral therewith an apertured flange 15 with which is threadedlyengaged a bolt 16 passing through one end of a clamping plate 17, whichplate 17 is adapted to engage the inner edge of the member 13 of thesash at one side of the pane 18, and as apparent, when the brackets 7are thus engaged with relatively opposite members 13 of the window sash19 the said frame 1 will be fixedly supported on the sash and extendtransversely 9 thereof as shown in Figure 3.

The carriage 2 comprises a plate like body 20 provided on its top sidewith a longitudinal groove, and on its under side'and adjacentrelatively opposite ends with pairs of apertured lugs 21 extendingtransversely thereof to receive the rods 6 as will be clear from a studyof Figures 8 and 9.

The sides of the groove in the top of the plate 20 are provided on theirinner faces medium of an adjustment screw or bolt 25 that is rotatablysupported as indicated generally at 26 on the upturned end of an arm 27projecting from'one end of the carriage 20, and this screw 25 has screwthreadedengagement with a lug 28 provided onone end of the slide orplatform 23. Obviously by r0 'tating'the screw'25 the platform 23 may bereadily shifted in the desired direction longitudinally of the channelin carriage 20.

On that end of the platform 20 remote from the lug 28 there are providedears 29 receiving a pivot bolt 30, and the bolt 30 also extends througha pair of ears 31 provided on the lower end of a combined guide and sup:porting member designated generally by the reference character 32.As'shown in Figure 10 the ears 31 on'their inner side are provided Iwith ratchet teeth or otherwise roughened as at 33 to cooperate withcorrespondingly roughened faces on the lugs 29 and thereby assistfoldable braces 34 in supporting the member 32 at the desired angularadjustment relative to the platform 23 The member 32 comprises sides 35on the lower ends of which are formed the aforementioned ears 31 and theupper ends of which are connected by a web that is extended andapertured as at 36 to provide a supporting means for an adjusting screw37.

On the inner faces of the sides 35 are grooves 38, and constrained toshift between the sides 35 is a block or slide 39 provided with tonguesor ribs 40 engaging the grooves '38. The slide or block 39 is alsoprovided with an apertured lug 41 with which is threadedly engaged thescrew 37, so that obviously by rotating the screw in the properdirection a slide 39 may be raised or lowered, or in other words shiftedlongitudinally of the number 32 as found desirable.

Suitably connected with the block 39, as by being integral therewith isa split clamping ring 42 that embraces and secures to the block 39 theelectric motor 4.

intermediate the ends of the platform. The

7 sections 34a, 34?) are pivotally connected together through the mediumof a bolt 45 with which is threadedly engaged a thumb nut 46, andobviously by tightening the thumb nuts 46, the sections 34a, 346 may besecured at the desired angular adjustment relative to one another andthereby brace and support the member 32 at its desired angularadjustment relative to the platform 23 as will be clear from a study ofFigures and 8.

As is well known in the art, when weather stripping a window with metalWeatherstrip, metal strips provided with ribs are secured to the innerside of the vertical members of the window frame and also to the windowsill requiring agrooving of the side rails and lower rail of the lowerwindow sash and the side rails of the upper window sash, while the lowerrail of the upper window sash, and the top rail of the lower window sashare routed on one side thereof as suggested in Figure 11 for receivingstrips of metal Weatherstripping so constructed that when the window isclosed such strips coact to completely seal the space between the lowerrail of the upper window sash and the upper rail of the lower windowsash.

In using the present invention, both the the window sashes may beeffected, and for grooving purposes there IS suitably connected with thearmature shaft of the motor-4 a cutter (S of the character shown inFigures 1 and 2, while for routing purposes a cutter of the charactershown at F igure4 is used. For groovlng purposes the frame 1, 1f 1t isdesired to groove a side rail 13, is, of

i course, extended longitudinally of the window sash, while, and asshown in F igure3,

if it is desired to groove the lower rail 13a of the lower window sash,the frame 1 is so a supported on the sash as to extend transverselythereof. Assuming that it is desired to groove the lower rail 13a theframe 1 is sup-' motor when viewed in Figures 1 and 2, is, disposedsubstantially at right angles to the sash 19 so that the cutter 5 issuitably engaged with the rail, and obviously in carrying out thegrooving operation the carriage 2 is moved longitudinally of the frame 1from one end to the other of the sash rail, and drive being transmittedto the cutter 5 from the motor 4 a grooving of the rail longitudinallythereof is easily accomplished. Obviously by adjusting the block 39 thegroove made by the cutter 5 and designated by the reference character 47may be formed in the under side of the rail adjacent either the front orrear face thereof or at any point midway between said faces.

For routing purposes the cutter shown in n f grooving and routing of theproper rails of Figure 4 is substituted for the cutter shown in Figures1 and 2, and since in routing oper ation the groove formed is cut on abias, the member 35 is secured at the desired and necessary angularrelation with respect to the platform 23 and the plane of the windowsash 19 as shown in Figure 4:, the adjusting of the member 32 beingeffected as hereinbefore stated.

In either grooving or routing operations the depth of the cut made maybe easily regulated by properly adjusting the platform 23 relative tothe carriage member 20, thus permitting such an adjustment of the depthof the out without requiring a shifting of the frame 1.
